Traumatic Brain Injury (TBI) affects almost 50,000 Hoosiers each year.  A TBI is an alteration of consciousness caused by an external force.  TBI is often not recognizable in MRI and CAT scans, as the insult or injury is too small to be picked up by diagnostic films.  Despite a small injury, it may cause a life of ongoing complications.  A TBI is a lifetime ongoing disease process that can only get worse in the future.  The experts agree, including the Brain Injury Association of America, Wounded Warriors, National Institute of Health, Department of Defense, etc.  In other words, visual damage to a brain is not necessary to show brain injury.  Also, a concussion is a TBI.  As established in the NFL litigation, TBI may result in dementia, Parkinson's', and Alzheimer's.
